Yes sir ..
I too think the same way .
Pen Drive are much more useful than a CD ..
because .. the most added advantage .. is shape and size.. and data handling capability .. A re-writable Compact disk .. can have many scratches .. and its life is also very less .. But a pen drive or a usb flash drive .. is much better option .. because .. no wear and tear worry .. more data storage capacity .. and so many advantages are there ..
